Answer:
10.5
Step-by-step explanation:
0.25 x 14 = 0.5 x (0.5 x 14) = 0.5 x 7 = 3.5
<em>14 - 3.5 = 10.5</em>
The answer is 28 units squared
A^2 + b^2 = c^2
a = x
b = 14
c = x+10
x^2 + 14^2 = (x + 10)^2
( x^2 + 196 = x^2 + 20x +100 ) - x^2
( 20x +100 = 196 ) -100
( 20x = 96 ) / 20
x = 4.8
Answer:
S.A. = 1,017.36
Step-by-step explanation:
S.A. = 
12 x 12 x 3.14 = 452.16
3.14 x 12 x 15 = 565.2
565.2 + 452.16 = 1,017.36
Okay so your partner describes a situation that has a slope of NEGATIVE 5, not positive 5 as your teacher asked.
Instead, your younger brother could have started with 100 and GAINED 5 every month, instead of losing 5.
